This is a 20 minute job.
Removal:
Take off the windshield wipers.
Take off at least the drivers side black plastic cowl cover, between the hood and windshield.
Go inside the car and with the Key OFF, step on the brake pedal about 40 times to release all the pressure inside the acccum.
Next, using a extension and a hex bit socket, loosen the accumulator and take it up and away from the car. You'll have to reach down to get it and wiggle it out, but it will come easily.
Installation:
Wipe the threaded accuml insertion area clean with a lint free cloth.
Make sure the new accumulator has the o-ring in place.
If so, install the accum. in place and tighten by hand. Final tighten with the socket. I'm sorry, but I don't know a torque spec. but I'd guess 20 to 25 ft-lb.
Replace the cowl covers and wipers.
Turn the key and you'll hear the motor recharging the accum.
That's it.
